Not there at the same time but I'm thinking this needs to be tried as well. My new ladies will need to be christened anyway!
Another variation is you get a stack of shots, something sweet, that red one works well. Hand it to all the ladies. Tell them to sit on the side of the pool with feet dangling in the water and have them lean back. Guy is in the pool. Lady pours the shot between and/or over the breasts. Guy can choose to take the shot at the breast level, stomach level or where the sun don't shine. Depends on comfort level with the lady you are taking the shot off of First one is usually tame as people feel out what is acceptable. But then people figure out the variations. Maybe someone else doing the shot other than your significant other, ladies off ladies, etc. Lets just say things can get interesting. The best is even the shy / more conservative can participate and it is a good opportunity to 'get your feet wet' as you can just do the shot off the belly level with your significant other. In May and October last year we found those 'shy' couples were the first to be starting up the shots the next day lol
The Reverse Luge is fun too... Kneel and then sit on your knees on the bar stool at the swim up bar, with your back to your partner. Arch your back, have someone pour the drink down the middle of your back starting at your scapula, your partner collects the shot as far down as you wish.
Another fun one is the Beer bong Cancun style...Paulie said it was the best beer he ever had... Back to good ole Swinger, Swayer, Monogomater 2010!!! International Bikini Day at the Sexy Pool!
